` JOSEPH B. OKEY, OF INDIANAPOLIS, INDIANA, ASSIGNOI.v TO HIMSELF AND FERDINAND A., LEHn, or SAME PLAGE.

Letters Patent No. 112,071, dated February 21, 1871.

IMPROVEMENT IN CLOD-CRUSHERS.

The Schedule referred to in these Letters Patent and making part of the same.

I, J OsErl B. OKEY, ot' Indianapolis, in the county of Marion and State of Indiana, have invented cer- Vtain Improvements in (lied-Crushers, of which the following is a specification.

Nature and Objects of the Invention.

My invention relates to the construction ot'a series of' stationary teetlnwvith two cutting-corners toV each,- and adjusted so as to project between the rows of teeth on a revolving toothed roller.

By this arrangement the `stationary teeth perform the oiiice of cleaners to the revolvingroller, while their cutting-corners vlikewise act as shears, in conjunction with thel teeth on the roller, and will cut up cornstalks and weeds into short pieces at vthe same time that the toothed roller is pulverizing the clods and grinding the surface soil to powder.

General Description.

F is the frame of the revolving roller R. f and b are cross-bars that hold the two sides F tof gether.

AThe roller may be made of wood, -or any other ma? terial desired. It maybe three feet long, more orV `less,fand of any desirable diameter.

It journals into F F, fig. 2.

This roller is iilled with tapering teeth t t, substantially as shownin figs. 1 and 2, oi' any desirable length 'and shape, disposed in regular rows around the roller,

so as to leave spaces for the stationaryV teeth C C between them, (see fig. 2.)

lhe teeth't t may be made of iron, steel, or any other suitable material. They should be square on their front face, and should pla y close to the cutting'- corners K K on O.

The stationary teeth C, Iig. 2, may be made of iron, or part wood and part metal, the body of wood, and steel knives K K secured on its sides.

These cutting-corners may be placed on a line with each other, or the two edges of the saine tooth O may be on different horizontal lines, one an inch o1' so lower than the other. With them. so arranged a stalk or weed will be cut with less force than -it would require if these edges were on the saine plane.

These stationary teeth G O are bolted'to `the crossbar b', and project forward and curve a little under the roller R, (see iig, 3.) A'The dotted lines in this iigure show the place where vthe cross-bar b4 is fitted into C.

'0, in 6g. 3, shows thecutting-corners K K as they project down. Y

S1 and S2, in fig. 1, are seats for `the drivel', whose feet can rest on the cross-bar f, to which the tongue Tis secured. The rear end of the tongue is bolted to the bracket, which projects above cross-bar b.

It will he seen that when my clod-crusher is in operation, and the roller It is revolving, the teeth t ton It pass beteen stationary teeth 'C O in exactly the same manner that one blade o'f a pair of shears passes the other blade-commencing the cut at one end and finishing it at the other. The machine, in this way, ents up corn-stalks and weeds most thoroughly, and mixes them in the pulverized soil.

Claim.

cutters C (l,A their lowersurfaces being s'o formed as to present an acute angle with reference totheir sides,`

in combination with the teeth of a revolving cylinder,

Ithe latter heilig so constructed as to nearly lill the space between the stationary' ones, and thus, in conjunction therewith, fornrcutting-edges or devices, subv stantially as and for the pu'rpose set forth.
